Answer 1

Step one: 9÷1.5= 6

Step two: 3·6=18

The actual book is 18 inches tall and 9 inches wide

Answer 2

Answer:

18 inches tall.

Step-by-step explanation:

The width of an image of a book shown on a website = 1.5 inches

and length of the book shown on the website = 3 inches

The actual width of the book = 9 inches

Scale of the book image = $\frac{9}{1.5}$

   1 inches  = 6 inches

The actual length of the book = 3 × 6

                                                  = 18 inches.

The actual book is 9 inches wide and 18 inches tall.
